摘要
根据给水管网的水力特性,构造了以管段压力及管段流量为求解变量的优化设计目标函数,利用线性约束的特点,采用了优化效果明显的简约梯度法进行计算,通过目标函数变换,一次性解决了求解管径圆整的难题,并经过了实例验证。
In accordance with the hydraulic characteristics of water network, this paper advanced the objective - function of optimal design regarding pipe - flow and pipepressure as unknown variables. On the basis of specific property of the linear constraints, the effective obviously Reduced Gradient Method was used the subject, by the transform of objective function, the problem of standardizing diameter was solyed successfully.
